My invention relates to a fluid medium conditioner whereby a predetermined condition in a given medium may be maintained substantially uniform in practically a continuous process. It consists pr1mar1ly 1n passing a given medium through a device provided with means whereby a desired agent, or agents, may be added to that medium. Or conversely, absorptive, adsorptive, m or catalytic agents of a known atfinity may take the place of the addable agents above referred to so that an undesired substance or substances may be removed from the medium. My invention also contemplates re- 15 conditioning of these agents by the removal therefrom of the element, or elements, that they have abstracted from the aforesaid medium, and this may be done by either chemical or physical means. Instead of being ren conditioned it is within the purview of my invention to bodily remove these agents from the apparatus.

From the foregoing it is apparent that the uses to which this invention may be put are many. While primarily intended for de-hydrating air in order to deliver air of a predetermined condition suitable fora given use, it is obvious that it may be equally as well used to control conditions generally where a uniform and constant supply of a gas, vapor, or other fluid medium of a given character is necessary or desirable. It furthermore contemplates the control of condition, not only of contact, but of temperature as well, since the a.) proper temperature is often as vital-to a given process as the presence of certain constituent elements.

In the accompanying drawings, which forms a partof this specification, is shown, more or less diagrammatically a device which employs my invention in the treatment of air so that air definitely controlled as to moisture and temperature is continuously discharged from the delivery end of the apparatus.

In said drawings, in which the same ref.- erence character refers to thesame element in each of the several views- ;l ig. l is a side elevation, partsbeing partially cut away to show the internal structure,

Fig. 2 is a plan view, also showing certain parts partially cut away, and

Fig. 3 is a transverse, vertical cross-section showing more in detail the structure indicated in Fig. 1.

Referring more specifically to the drawings, is a casing in which is housed a circular carrier 11, serving as an endless conveyor, to be fully described later, mounted to rotate on hollow trunnions 12 which are held stationary in bearings 13 provided at the top of frame standards 14. To the stationary trunnions on the inside of the carrier is mounted rigid yoke 35. This yoke 35 serves as a support to hold rigid the compartment divisions on the inside of the carrier, also as a stiffener for standards 14. The carrier 11 is divided into compartments, fora reason which will appear later, and the driving mechanism is provided with suitable means to give an intermittent or step by step movement, which in the drawings are shown as Geneva-movements 15 driven froma motor 16 by suitable transmission means indicated in a general way by numeral 17. Motor 16 also serves to drive a fan, not shown, mounted in casing 18. This casing discharges air or other medium forced into it by the fan therein into medium compartment 36, through medium inlet ports 19 which are controlled by louvers 20, through carrier compartments 21 into medium compartment 37, thence again through carrier compartments 21, andfinally through ports 41 and throughtempering compartment 24. i

It is evident when a product is to be of uniform consistency with the ingredients at variance, the process is to be adjusted accordin gly, for which reason medium compartment 36 is provided with by-pass port 39 which port 39 is controlled by suitable by-pass damper 40, medium inlet ports19 are also provided with suitable louvers as heretofore described, the medium outlet ports 41 are also provided with suitable'louvers 25, 'to be fully; described'later. By-pass damper 40, medium inlet louvers 20 and medium outlet louvers .25 are adjustable and can be operated either individually or simultaneously by means of suitable mechanism 42, which mechanism 42 is actuated by means of control lever 34. Fig. 1 shows the medium inlet louvers 20 and medium outlet louvers 25 not exactly wide open while medium by-pass damper is restricting the opening of medium by-pass port 39, which indicates when in this position not all of the medium forced into chamber 36 will have to be modified by modifying agents, but a portion of unmodified medium will pass through by-pass port 39 and mingle again with modified medium that the number of compartments 21 may be' varied as conditions may dictate. The air or other medium undergoing modification having been acted upon by the materials in receptacles 22 passes into the tempering compartment 24 through ports 41 which are controlled by suitable louvers 25, thence over the tempering coils 26, to be delivered to any desired point.

Some reconditioned air, or other medium, is passed from chamber 27 through flue 28 and a suitable duct (not shown) to port 32 of the outer portion of reconditioning chamber 30, and tempered air is transmitted from tempering chamber 24 by a suitable duct (not shown) to port 33 of the outer portion of reconditioning chamber 31. From these outer portions of the reconditioning chambers the reconditioned and tempered air passes through receptacles 22 to the inner portions of said chambers 30 and 31 these being commingled through port 45, (Fig. 3).

The air passing through receptacles 22 tends to cool the hot agents and consequently will recondition same for the next cycle.

In the partition 44 between the inner reconditioning chambers 30 and 31 are placed openings 45 of proper size to let a corresponding amount of air pass from the inner reconditioning chamber 31 into inner reconditioning chamber 30. In partition 47 which separates reconditioning chamber 30 from heating compartment 29a is placed air conduit to heater 29.

Outer reconditioning chamber 30 is formed by partitions 44 and 47, (see Fig. 3), While reconditioning chamber 31 is formed by partitions 43 and 44. 46 is in effect a continuation of partition 47 and serves to prevent in- 27 having a flue 28 at its top and an opening at its base of substantially the same size as compartment 21. Directly underneath this hood 27 is a heating chamber 29a in which is a heater 29, which may be heated by hot air, steam, gas or electricity, the function of the heater being to drive ofi the absorbed or adsorbed material from agents in receptacles 22. The material driven off from said agent, if so desired, may be either collected or expelled after leaving flue 28. Casing 10 is also provided with reconditioning chambers 30 and 31 referred to above, in which matter necessary to a given process may be added to the materials in receptacles 22, the same being delivered to chambers 30 and 31 through ports 32 and 33.

It is believed the foregoing description fully sets forth the operation of my invention. It is to be noted that my invention is capable of application to all those technical and industrial processes that demand for their most effective operation a stable condition of air or other medium, and is especially valuable in dairies, cheese-factories, dyeing establishments, abattoirs, hospitals, laundries, photographic film manufacture, enameling works,

last furnaces, textile industries, theatres, etc, because of the capacity of the apparatus to modify the condition of the air, or other medium, passing through the modifier by reason of the possible variation in speed of the carrier conveying the modifying agent, and the adjustable character of the dampers through which the air is passed over the modifying a ent. Furthermore, the control is enhanced by the tempering coils after the predetermined chemical, or chemico physical, character of the air has been effected.
